We read with interest the recent article by Huang et al,1 who stated “To our knowledge, this is the first study to demonstrate that the postoperative reduction in IOP [intraocular pressure] is related to the increase in angle width after phacoemulsification for NA [narrow-angle] and OA [open-angle] eyes.”1 It seems relevant to highlight work by Dooley et al,2 which also reports changes in the anterior chamber angle (ACA) and IOP following phacoemulsification; while not mentioned in the discussion by Huang et al, it may be complementary to this work.
